Abstract
PURPOSE:To obtain a magnetic recording substance which excels in the travelling performance and the durability, by mixing a lubricant containing both the mineral oil and the fatty acid into a magnetic layer. CONSTITUTION:The mineral oil having the <=300cs viscosity at 37.8 deg.C such as the spindle oil #1 and #2, refrigerating machine oil #1-#3, turbine oil #1-#4, class-1 gear oil #1-#4, class-2 gear oil #1-#4, machine oil #1-#3 and the like plus the fatty acid having 12-22 carbon number such as the oleic acid, myristic acid or the like are contained in a magnetic painting material. Such material is coated on a substrate to obtain a magnetic recording substance.
